Alright, so right now I have a stock Classic Army G36K + Long rails and vertical front grip (see signature picture). Now, basically what I
want to do over time is set it up to look something like this:

In a nutshell, G36C carry handle/top rail, and an Eotech+Magnification sight setup...
I'm just wondering how efficient this would be? I prefer outdoor, but I hear Eotech is the way to go, since I can either remove or flip aside the magnification scope for indoor... Ideas? Suggestions?
